OF YOAKUM, TEXAS.

COTTON-SEED SEPARATOR.

SPECIFICATION forming part of Letters Patent No. 769,711, dated September 13, 1904.

Application filed June 18, 1903.

To In whom 7'25 nuty concern.-

Be it known that I, FRANCIS T. PINTER, a subject of the Emperor of Austria-Hungary, residing at Yoakum, in the county of Lavaca and State of Texas, have invented new and useful Improvements in Cotton-Seed Separators, of which the following is a specification.

My invention relates to improvements in Cotton-seed separators, and pertains more partlcularly to a device for separating the large seeds from the small ones for planting.

My invention consists in a separator of this character having a reciprocating or sliding screen having a rotary drum or Sifter thereabove and the reciprocating and rotary sifter so arranged in combination with each other that the grain can be either passed through either one or both, as desired, and at the same time be thoroughly separated.

In the accompanying drawings, Figure 1 is a perspective view of my improved separator. Fig. 2 is a top plan view. Fig. 3 is an end view partly in section.

Referring now to the drawings, A represents an elongated frame which is provided with the vertical side walls Ii and B, having their inner sides provided with the horizontal grooves I) and 7/, extending from end to end. Between said vertical side walls B and B is a sifter-box (l, which snugly fills the space between the said wall, and said box C adjacent its lower edge is provided with the outwardlycxtending ribs or flanges c and c, which are adapted to enter the grooves and I), and thus the said box G is adapted to slide or reciprocate therein.

Pivotally connected to the end of the frame A is a lever l), which has pivotally connected thereto intermediate its ends a rod D, which passes through an elongated slot (Z in the forward end of the box 0, and the end of said rod 1 is secured to the rear end of the box C, and thus it is seen that the lever will reciprocate the box C. The bottom of the box C is covered with a wire-netting E, or it may be made of sheet metal having openings 0 of any size or shape punched therein. The rear end of said box C is provided with a cut-away portion (1, which allows the large cotton-seed that Serial No. 162,056. No model.

5 cannot pass through the openings in the netting E to pass therefrom.

The sides of the frame A are provided with the two sockets or U-shaped clips G. which may be rigidly secured thereto by means of bolts or screws, as desired. Resting in said sockets or clips Gr are the supports H and H, which are preferably made of heavy wire or rods, which are formed in the shape of an inverted U, and each support is provided with a round loop 71 and 12-, which is preferably made by the same piece of wire out of which the support is made. The vertical portions of said U-shaped members are provided with stops 1, which prevent the said portions from passing through the loop or clips G, and thus they are removably supported therein, yet they cannot be accidentally removed, as the weight of the drum or cylinder J (hereinafter described) is such that it requires a great upward pressure to raise the members H and H out of the sockets G. The loop h is a little lower than the loop /t, and thus when the cylinder J is mounted therein one end is slightly lower than the opposite end. The cylinder J is preferably made of wire-nettingj, carrying at each end a solid metal portion K and K, which is adapted to act as a hearing or solid portion, upon which it is adapted to rotate in the round loops /1 and /1.', and said solid portions are slightly concaved in order to wise therein. rings are provided with upwardly-projecting ears M and M, in which is rotatably mounted a longitudinal shaft N, which carries adjacent its outer end a pinion O, which meshes with a gear-wheel P, rigidly mounted upon or surrounding the cylinder. The extreme end of the shaft N carries a crank Q, by means of which the shaft and pinion O is revolved, and thus the cylinder is caused to revolve also.

The cotton-seed is fed to the end of the cylinder opposite to that carrying the gear, and the mesh of said cylinders is such that it will allow all of the seeds to pass therethrough but the trash, &c., which will continue to travel and be discharged from the end of the cylinder beyond the end of the sieve-box C,

prevent the said cylinder from moving end- A The upper portions of said as it is seen that the end of the cylinder is of such a length that it extends beyond the most outward movement of the sieve-box C, and thus the trash is discharged clear of the box 0. The cotton-seed all passes from the cylinder together with the fine portion of the trash or dirt; but the reciprocation of the sieve-box C causes all of the small seeds and dirt to pass therethrough, while the large and perfect seed pass to the rear end and are discharged through the opening 0 into a receptacle placed below for that purpose. When the cylinder is removed and the seed fed to the reciprocating sieve-box, they would be fed adjacent the forward end in order that all small trash and seeds may pass therethrough; but in this case the larger trash that could not pass through the screen would pass out with the large or perfect seed.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination with a supporting-frame, of a reciprocatingsieve-frame within the supporting-frame and extending above the same, upwardly-extending removable supports carried by the side of said supporting-frame, rings formed in said supports above the reciprocating frame, and a rotary screen within said rings above the reciprocating frame.

2. The combination with a supporting-frame, of a reciprocating sieve-frame within the supporting-frame and extending above the same, upwardly-extending removable wire-supports carried by the side of said supporting-frame, rings formed in said supports, above the reciprocating frame, a rotary screen within said rings above the sieve-frame and concaved plates carried by the rotary screen beneath said rings.

3. The combination with a supporting-frame, of a reciprocating sieve-frame therein, sockets carried by the sides of said supporting-frame, a rotary screen-supporting frame above said sieve-frame, and downwardly-extending arms carried by said rotary screen supporting frame and removably held within the sockets carried by the sides of the supporting-frame.

L. The combination with a supporting-frame, of a reciprocating sieve-frame therein, sockets carried by the sides of said supportingframe, removable inverted U shaped wire members having their lower ends resting in said sockets, rings formed in the said wire members, a rotary screen within said rings and concaved bearing-plates carried by the rotary screen beneath said rings.

5. The combination with sieve-supporting frame, sockets carried by the sides of said supporting frame, removable inverted U- shaped wire members having their lower ends resting in said sockets, sleeves surrounding said ends adapted to limit the downward movement therein, rings formed in the upper ends of said U-shaped wire members and a rotary screen mounted in said rings.

In testimony w hereof I have hereunto set my hand in the presence of two subscribing witnesses.
